Tropical Storm Lorenzo formed over the central tropical Atlantic Ocean on Monday morning, At 5:00 a.m. EDT on Monday the center of Tropical Storm Lorenzo was located at latitude 14.2°N and longitude 40.3°W which put the center about 1095 miles (1760 km) west of the Cabo Verde Islands. Lorenzo was moving toward the northwest at 17 m.p.h. (28 km/h). The maximum sustained wind speed was 45 m.p.h. (75 km/h) and there were wind gusts to 60 m.p.h. (95 km/h). The minimum surface pressure was 1006 mb.
A low pressure system over the central tropical Atlantic Ocean west of the Cabo Verde Islands strengthened on Monday morning and the U.S. National Hurricane Center designated the system as Tropical Storm Lorenzo.
More thunderstorms were forming near the center of Tropical Storm Lorenzo on Monday morning. Thunderstorms were also occurring in bands in the northern and eastern parts of Lorenzo’s circulation. Bands in the southern and western parts of Lorenzo consisted primarily of showers and lower clouds. Storms near the center of Lorenzo began to generate upper level divergence that pumped mass away to the north and east of the tropical storm.
The strongest winds were occurring in the northeastern part of Tropical Storm Lorenzo. Winds to tropical storm force extended out 90 miles (145 km) in the northeastern quadrant of Lorenzo’s circulation. The winds in the other parts of Tropical Storm Lorenzo were blowing at less than tropical storm force.
Tropical Storm Lorenzo will move through an environment somewhat favorable for intensification during the next 24 hours. Lorenzo will move over water where the Sea Surface Temperatures are near 27°C. It will move under the eastern side of an upper level low that is northeast of South America. The upper level low will produce southwesterly winds that will blow toward the top of Lorenzo’s circulation. Those winds will cause moderate vertical wind shear. The vertical wind shear will inhibit intensification, but the wind shear may not be enough to prevent intensification. Tropical Storm Lorenzo could intensify during the next 24 hours if the upper level winds do not get any stronger.
Tropical Storm Lorenzo will move around the eastern side of a high pressure system that is over the eastern Atlantic Ocean. The high pressure system will steer Lorenzo toward the northwest during the next 24 hours. On its anticipated track, Tropical Storm Lorenzo could approach the Azores at the end of the week.
